// a game properly so I guess this is what we're left with. The launcher process
// acts as a giant try-catch statement around the entire of GTA, so if GTA crashes
// or is killed by force, the launcher process will pop up with the usual 'safe mode'
// message.
//
// The problem with this is that the launcher needs time to start up, as it seems as if
// it sets a flag of some kind to tell itself that it has already prompted the user with
// the 'safe mode' warning message. If the launcher process never has time to initialize when
// the game is killed, then it never gets to set the flag to say it warned the user.
// As a result of this, the next time the game is started, because it relies on the launcher
// process to instance the game, it will show up the 'safe mode' dialog and stop us from
// launching the game until the dialog is dealt with.

// Get the launcher process, this is needed because GTA is special and will try to
// catch all exceptions that occur, and pop up an annoying 'Safe Mode' dialog. This is
// annoying and useless, we have no other way to stop GTA quickly other than a force
// quit so this dialog is expected. If we find it, kill it. It serves no purpose for us.
